忘了sudo
:w !sudo tee % > /dev/null
:w !{cmd} # 执行外部命令{cmd} 并将当前缓冲区内容从标准输入传入
sudo tee > /dev/null # 将标准输入输入输出到文件并忽略标准输出
% # %是vim中保存当前编辑文件路径的只读寄存器
PHP扩展
echo 'extension=swoole.so' >> $(php -i | grep 'Loaded Configuration File' | awk -F '=>' '{print $2}')
php -i | grep 'Loaded Configuration File' # 筛选php配置信息: Loaded Configuration File => /Users/kevin/.phpbrew/php/php-7.1.15/etc/php.ini
| awk -F '=>' '{print $2}' # 指定'=>'分隔符打印第二个元素
echo 'extension=swoole.so' >> # 将字符串追加输出到指定文件
man awk
